摘要
本文用一步法合成了新化合物RbEuI_3与CsEuI_3,测定了化合物的组成、结构、熔点、密度、荧光光谱、极谱电位及磁矩,确定了化合物中Eu的价态为正二价.
The synthesis of AEuI3 (A = Rb, Cs) by a one-step method has been reported. The europium valence, which was determined from the magnetic moment and by polarography, is 2+. The structure of these compounds were determined by X-ray powder diffraction. The composition, lattice parameters, melting point, density, magnetic moment, polarographic potential and fluorescence spectra of AEuI3 have been presented.
